Multi-recast techniques make it possible for a voter to participate in
a sequence of different designated votings by using only one ticket.
In a multi-recastable ticket scheme for electronic voting, every voter
of a group can obtain an m-castable ticket (m-ticket), and through th
e m-ticket, the voter can participate in a sequence of m different des
ignated votings held in this group. The m-ticket contains all possible
intentions of the voter in the sequence of votings, and in each of th
e m votings, a voter casts his vote by just making appropriate modific
ations to his m-ticket. The authority cannot produce both the opposite
version of a vote cast by a voter in one voting and the succeeding un
cast votes of the voter. Only one round of registration action is requ
ired for a voter to request an m-ticket from the authority. Moreover,
the size of such an m-ticket is not larger than that of an ordinary vo
te. It turns out that the proposed scheme greatly reduces the network
traffic between the voters and the authority during the registration s
tages in a sequence of different votings, for example, the proposed me
thod reduces the communication traffic by almost 80% for a sequence of
5 votings and by nearly 90% for a sequence of 10 votings.
